GeoBox image stacking processor instroduction
Image stacking is an easy way to increase the brightness at low cost. It also provides a spare function when one of the projectors is broken down without affection important event. GeoBox stacking processor not only provides flat screen stacking function, it can also support curved screen stacking and serve as scaler switcher due to convenient multiple inputs. It will work with all kinds of projectors with different brands. No PC is required, easy to use and more reliable.
Image stacking can increase the projection brightness easily by 2x, 4x, 6x....User can get 10k lumens by using 3 projectors with 3,500 lumens paired with one G-601. Using GeoBox warp technology, user can stack more projectors to get more brightness with fraction of cost. By using G-601, which is designed with 5 inputs and 10-bits high end video processor, user can get a stacking system with multiple projectors together with high end scaler box, format converter and video switcher function in one box. Another major advantage is that even some projectors are broken down, user still can keep the system running without affect important events.
Image stacking function can be applied on both flat screen and curved screen with large and flexible geometry adjustment range. For output resolution under 1400x1050, the corner position or curve adjustment range can be up to +_1200 pixels in horizontal position and +_800 pixels in vertical position.

* The specifications are subject to change without prior notice.
* Installation method: Apply external grid pattern, 1st projector is aligned manually to fit the screen and the 2nd/3rd projectors are aligned to match the 1st one via GeoBox geometry alignment. The latency in GeoBox is about 30 ms. If no latency is allowed in each projector, then all channels need to go through GeoBox. In this case, dual channel processor is required for two projector image stacking. Multiple Geobox can be synchronized by Frame Lock function.
